Ziggy had a rough start as a puppy, but 3D printing technology and a couple of clever people have helped him get up and running again. The two-year-old Border Collie was found abandoned in 2014 as a puppy, with a broken front leg that wasn’t correctly healing and required amputation. At three months old, Australian couple Rebecca Colvin and Glenn Althor adopted him from the animal protection agency, the RSPCA.
